The invention relates to an energy storage device for providing electrical energy, having a cell assembly. The cell assembly has at least three or more interconnectable, substantially cuboidal electrochemical energy storage apparatuses, each having a first edge length. The second energy storage apparatus is arranged between the first and the third energy storage apparatus. The energy storage device furthermore has a temperature control apparatus which is designed for controlling, and in particular for maintaining, the temperature of the cell assembly. The temperature control apparatus has a base plate which can be cut to length by a first, in particular plate-shaped blank, in particular designed as a continuous casting profile. The base plate or the first blank have at least two liquid channels for conducting a temperature control liquid. The at least two liquid channels extend at least in sections through the base plate or the first blank. The base plate can be connected at least to the at least one second energy storage apparatus in a thermally conductive manner. The temperature control apparatus has at least one, in particular substantially plate-shaped liquid conducting apparatus, which can be connected to the base plate in a thermally conductive, in particular bonded manner. The liquid conducting apparatus is designed to have at least one third liquid channel for exchanging the temperature control liquid with one of the liquid channels, in particular for transferring the temperature control liquid from the first liquid channel to the second liquid channel. The at least one liquid conducting apparatus can be connected to the first or the third energy storage apparatus in a thermally conductive manner. The temperature control apparatus has at least one or two connecting apparatuses which can be connected to the base plate, preferably to the at least one liquid conducting apparatus, in particular in a bonded manner. The at least one connecting apparatus can be cut to length by a second blank. The at least one connecting apparatus or the second blank has a plurality of first connecting means, arranged at a predetermined grid spacing from each other, for mechanical, in particular removable connection to at least one of, or a plurality of the energy storage apparatuses. The predetermined grid spacing substantially corresponds to the first edge length of the energy storage apparatuses. |
